Investigators say 42-year-old Zerrick Brown is charged with the first-degree murder of Coltrane. And the news is just what Coltrane’s family members needed to hear:

"We're relieved and thankful and grateful to MPD," says Charles Shelton. "We weren't too hopeful at first...the surveillance video was grainy, and you couldn't tell the suspects' identities, you couldn't tell who they were."

Early Tuesday morning, the 60-year-old had run an errand at the 7-Eleven on 8th and E Streets on Barracks Row. Two men came inside the store, grabbed Coltrane, and dragged him out of the store before beating and robbing him of $60. Coltrane died from his injuries three days later.

Coltrane’s neighbors have been uneasy about the brutal crime. Coltrane was a retired musician who was partially disabled, and walked with a cane.

"Ultimately it's a severe price to pay for such a small thing," says Tim Chamberlain. "It's great to hear that the police are being active and that they've had some success."

But police are still searching for the second suspect, seen in the video wearing dark clothing. The victim’s family is hoping the public can help track him down soon.
